Jesse tossed a paint brush off her roof. The height of the brush (in meters above the ground) ttt seconds after Jesse tossed it is modeled by h(t)=-5t^2+5t+10h(t)=−5t 2 +5t+10h, left parenthesis, t, right parenthesis, equals, minus, 5, t, squared, plus, 5, t, plus, 10 Jesse wants to know when the brush will hit the ground. 1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation. h(t)=h(t)=h, left parenthesis, t, right parenthesis, equals 2) How many seconds after being thrown does the brush hit the ground?
